[AS3]as3和js分别判断用户终端的浏览器类型的方法实例

JS的写法

function getBrowser(){ 
    
      var useragent = navigator.userAgent.toLowerCase(); 
 
       if(/(.*)maxthon(.*)/.test(useragent)){ 
           document.write('遨游'); 
       } 
       else if(/(.*)firefox(.*)/.test(useragent)){ 
           document.write("火狐"); 
       } 
       else if(/(.*)chrome(.*)/.test(useragent)){ 
           document.write("谷歌"); 
       } 
       else if(/(.*)msie(.*)/.test(useragent)){ 
           document.write("IE"); 
       } 
       else if(/(.*)mozilla(.*)/.test(useragent) && !/(.*)firefox(.*)/.test(useragent) && !/(.*)chrome(.*)/.test(useragent) && !/(.*)msie(.*)/.test(useragent)){ 
           document.write("safari"); 
       }else{ 
            document.write("cuplayer.com未知"); 
       } 
        
       return useragent; 
    
   }
